<span>Flow rate through pipe a is 0.4 m3/s
Parallel pipes have a diameter D = 30 cm => r = 15 cm = 0.15 m
Length of Pipe a = 1000m
Length of Pipe b = 2650m
Temparature = 15 degrees
Va = V / A = (0.4m3/s) / (3.14 (0.15m)^2) = 5.66 m/s
h = (f(LV^2)) / D2g
(fa(LaVa^2)) / Da2g = (fb(LbVb^2)) / Da2g and Da = Db; fa = fb
LaVa^2 = LbVb^2 => La/Lb = Vb^2/Va^2
Vd^2 = Va^2(La/Lb) => Vb = Va(La/Lb)^(1/2)
Vb = 5.66 (1000/2650)^(1/2) => 5.66 x 0.6143 = 3.4769 m/s
Vb = 3.4769 m/s
V = AVb = 3.14(0.15)^2 x 3.4769 m/s = 0.245 m^3/s</span>
Refer to the diagram shown below.
The following discussion assumes a simplistic analysis that ignores air resistance and variations in the terrain that the missile travels over.
Let the launch velocity be V₀ at an angle of θ relative to the horizontal.
The horizontal component of velocity is V₀ cosθ.
If the time of flight is
, then
where r = the range of the missile.
Also, the time, t, when the missile is at ground level is given by
where g = acceleration due to gravity.
t = 0 corresponds to when the missile is launched. Therefore
Therefore
Typically, θ=45° to achieve maximum range, so that
This analysis is more applicable to a scud missile rather than a powered, guided missile.
Answer:
Usually, θ=45°
Answer:
Alcohol and drugs play a factor in sexual assault through bad ideas without education (such as committing the assault), as well as not being conscious when you are a victim of sexual assault.
No, because the evidence was offered before a grand jury, not a court is why the indictment can't be squashed.
<h3>What is Indictment?</h3>
This is referred to when an individual is accused of a crime. The evidence is usually brought before a grand jury which comprises of grand jurors.
A grand jury votes an indictment if at least 12 grand jurors see enough evidence against the individual which is why it can't be squashed.

Answer:
7.95 meters
Explanation:
The magnitude of a vector can be found with Pythagorean's theorem:
v² = vx² + vy²
v² = (-7.55)² + (-2.48)²
v² = 57.0 + 6.15
v² = 63.15
v = 7.95
The magnitude of the vector is 7.95 meters.
